1.Why the “SPI Fault” displaying on the inverter screen?
Cause of occurrence:
The cause of this fault is a communication problem between the main and secondary CPUs of the inverter control board.
Solution：
(1) Restart the inverter (you need to disconnect the PV, AC grid, and batteries and then turn it on again).
(2) If the problem persists after restarting the inverter, check if the software version of the inverter control board is correct. If not, try to burn in the software again.
(3) If the problem persists after burning the software, replace the control board.

2.The inverter displays a grid error and shows the fault message as voltage error "Grid Volt Fault" or frequency error "Grid Freq Fault" "Grid Fault"?
Cause of occurrence:
The voltage and frequency of the AC power grid are out of the normal range.
Solution:
Measure the voltage and frequency of the AC power grid with the relevant gear of the multimeter, if it is really abnormal, wait for the power grid to return to normal. If the grid voltage and frequency are normal, it means that the inverter detection circuit is faulty. When checking, first disconnect the DC input and AC output of the inverter, and let the inverter power off for more than 30min to see if the circuit can recover by itself, if it can recover by itself, you can continue to use it, if it can’t be recovered, you can contact Renac for overhaul or replacement. Other circuits of the inverter, such as the inverter main board circuit, detection circuit, communication circuit, inverter circuit, and other soft faults, can be used to try the above method to see if they can recover by themselves, and then overhaul or replace them if they can not recover by themselves.

3.Excessive output voltage on the AC side, causing the inverter to shut down or derate with protection?
Cause of occurrence:
Mainly because the grid impedance is too large, when the PV user side of the power consumption is too small, the transmission out of the impedance is too high, resulting in the inverter AC side of the output voltage being too high!
Solution:
(1) Increase the wire diameter of the output cable, the thicker the cable, the lower the impedance. The thicker the cable, the lower the impedance.
(2) The inverter is as close as possible to the grid-connected point, the shorter the cable, the lower the impedance. For example, take 5kw grid-connected inverter as an example, the length of the AC output cable within 50m, you can choose the cross-sectional area of 2.5mm2 cable: the length of 50 – 100m, you need to choose the cross-sectional area of 4mm2 cable: length greater than 100m, you need to choose the cross-sectional area of 6mm2 cable.
